CVE-2024-3272
Published: April 11, 2024
Official Description
D-Link DNS-320L, DNS-325, DNS-327L, and DNS-340L contains a hard-coded credential that allows an attacker to conduct authenticated command injection, leading to remote, unauthorized code execution.
CISA KEV Advisory
D-Link Multiple NAS Devices Use of Hard-Coded Credentials Vulnerability
D-Link DNS-320L, DNS-325, DNS-327L, and DNS-340L contains a hard-coded credential that allows an attacker to conduct authenticated command injection, leading to remote, unauthorized code execution.
This vulnerability affects legacy D-Link products. All associated hardware revisions have reached their end-of-life (EOL) or end-of-service (EOS) life cycle and should be retired and replaced per vendor instructions.
Risk Analysis
D-Link DNS-320L, DNS-325, DNS-327L, and DNS-340L devices contain hard-coded credentials, enabling an attacker to perform authenticated command injection and achieve remote code execution. The very high EPSS score of 0.94168 indicates a strong likelihood of exploitation, making this a critical vulnerability. This vulnerability is confirmed to be actively exploited.
This vulnerability is actively exploited in the wild and is listed in CISA's KEV catalog. The presence of hard-coded credentials allows for straightforward remote exploitation.
Update affected D-Link DNS devices to the latest firmware provided by the vendor. Implement strict network segmentation and access controls to prevent unauthorized access to these devices.
Technical Analysis
CVE-2024-3272 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
CISA has added CVE-2024-3272 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
